Application March 26, 1953, Serial No. 344,815 3 Claims. (Cl. 219-46) 2,718,585 Ce Patented Sept. 20, 1955 means of which main switch the supply of electric energy to all of the resistance elements in the device and the intensity of the supplied energy are simultaneously regulated, irrespective of whether or not only one, two or all independent resistance elements are being energized,

' and which main switch is adapted to automatically cut out the supply of electric energy when any part of the heating device reaches a certain maximum temperature.

The foregoing and numerous other objects of the present invention will become more fully apparent from the ensuing description in conjunction with the accompanyaim of that invention is the relief of colds, headaches,

sinus and other ailments by the application of heat to the head areas. In extending experiments with that device, it has been determined that when heat is applied to the neck and ear areas as well as to the shoulders, the upper frontal chest and the bronchial chest areas, deepseated cold affections often resulting in serious ailments become readily relieved.

The prime object of the present disclosure therefore is the provision of a combination heating device which will provide controllable warmth to the neck, the ears, the upper shoulder areas, the upper chest areas and to the bronchial chest area, and which device is relatively simple and inexpensive in construction but'very effective in its use.

in a combination heating device of the type indicated of a. main section comprising a heating pad covering the shoulder and the upper chest areas and the bronchial chest area, and with which main section there is associated an adjustable band-like neck section adapted for heating the neck, and from which neck section extends a pair of ear heating flaps, and wherein the upper portion of the main section and the neck section have a common, continuous resistance element, and wherein individual resistance elements are provided for each of the ear flaps and the bronchial chest portion of the main section.

A further object of this invention is the provision of a combination heating device comprising a main section for applying heat to the upper shoulder portions, the upper chest portion and the' bronchial chest portion, and to which main section is fixedly attached a relatively wide, adjustable band-shaped neck-enclosing section from which extend ear covering flaps, and wherein the attachment of the neck section to the main section is effected along the lower edge of a relatively short end portion of the neck section, the line of attachment extending from one of the shoulder areas to approximately the center of the upper frontal chest area of the main section, the neck section thus forming a relatively short fixed end portion and a substantially longer free mobile portion which is adjustable relative to and is adapted to cooperate with the fixed end portion of the neck section, and wherein means are provided at the adjustable mobile portion and at the other upper shoulder area of the main section to detachably hold the mobile portion against .the main section after adjustment of the neck section.

A further object of this invention is the provision within the ear flaps and within the bronchial chest portion of the main section of independent and independently controllable resistance elements which are connected in parallel, as is also the resistance element for the main and neck sections.

A still further object of this invention is the provision of a thermostatically controlled main switch interposed between the main supply line and the heating device, by

ing drawings forming an essential part of the present invention, but being intended primarily for the purpose of explaining the instant device, without restricting it to the actual showing, and wherein:

Fig. 1 illustrates a heating device-in accordance with the present invention; and I Fig. 2 shows an electric diagram indicating the various heating elements employed in the several parts of the device and their controls and connections with the main supply source.

A further object of this invention is the provision withrest of the neck section is free and mobile.

As illustrated, the device comprises a mainsection 10 having sub-sections 11 and 12 adapted to cover the upper shoulder areas, sub-section 13 for the upper frontal chest area and sub-section 14v applied to the bronchial chest area. Secured to the upper edge along a relatively short line extending from shoulder section 11 to approximately the center of the upper frontal chest area is a neck section 15 comprising a relatively wide adjustable neck-encircling band 16 and a pair of ear flaps 17 and 18 extending upwardly from band 16.

As will be seen in Fig. 1, a relatively short frontal portion of the lower edge of band 16 is fixedly secured to main section 10 as indicated at 19, whereby the neck section is formed into a fixed end portion 20 while the That mobile portion of the neck section terminates in an adjustable end 21, there being provided on both portions 20 and 21 cooperating snap fasteners or any other suitable connecting means 22 adapted to facilitate adjustment of the neck section to varying sizes. Adjustable end portion 21: is provided with a tab 23, adapted to engage button- 24 afiixed to main section 10 at a point adjacent shoulder area 12. The tab and button serve for detachably securing the neck section to main section 10 after adjustment of the neck section is effected. Obviously any other suitable means for holding the neck section against the main section in the vicinity of shoulder area 12 may be employed.

In the electrical diagram of Fig. 2 there is shown a main resistance element 25 which is adapted for heating the shoulder areas, the front upper chest area and the neck. The portions of resistance element 25 for heating the shoulder areas are indicated at 11 and 12', those portions for heating the upper frontal chest area are marked at 13 and the portions for heating the neck are denoted at 16'. There is provided an independent element 14 for heating the bronchial chest area, and independent heating elements 17 and 13' are designed for heating the two ear flaps 17 and 18, respectively. All of the three independent heating elements are equipped with individual, manually operable switches. Thus switch 26 serves heating element 14, and the ear flap heating elements are controlled by switches 27 and '28.

The supply of energy to the several heating elements is elfected by main supply line 29 composed of two conductors 30 and 31 which are connected with thermostatically controlled main switch 32. The latter governs the supply of energy simultaneously to all of the resistance elements. Extending from main conductors 30 and 31 are branches 32 and 33 leading to resistance element 14 for the bronchial area. These branches are independent- 3 1y controlled by switch 26. Other branches 34 and 35 supply current to the two ear flap resistances which are individually controlled by switches 27 and 28. Although the individual switch controls for these ear flaps are not absolutely essential, it is preferred to provide them, however they 'may be readily omitted.

As has been said above, main switch 32 is thermostatically controlled so that when any part of the heating device reaches a certain maximum temperature, switch 32 will automatically either cutoff or substantially reduce the intensity of the current supply to the heating device. Such instruments as switch 32 are well known in the art and need not be explained and do not constitute a part of the present invention except as to its location in relation to the difierent resistances of the heating device. Howevergmain switch 32 is so arranged that'it will control the supply of current to the heating device irrespective of whether all, any number'of or any one of the resistances are in use. Since the resistance element of the main section has no specific control, main switch 32 is relied upon to permit the heating of the shoulder areas, the frontal upper'chest portion'and the neck to the desired temperature to whichthe main switch is adjusted. As will be seen from Fig. 2 main switch 32 is provided with a movable indicator 36 which may be set to any one of three positions or to the off position, at which latter no current is supplied to the heating device.

The adjustability of neck section 15 not only provides the possibility of using thedevice for different neck sizes, but also facilitates the distancing of neck band 16 and of ear flaps 17 and 18 in respect to the neck and ears, thereby regulating, in addition to the control by switch 32, the intensity of heat applied "to these body areas.

While the drawings show a specific construction of the present heating device as well as a specific electric diagram indicating the arrangement and location of the different resistance elements, it is quite obvious that changes both in the physical structure of the device as well as in its electrical connection and control may be required, for instance, the two ear flaps 17 and 18 may be connected'by a continuous unheated web to provide a more substantial support for them, although the flaps can be sufficiently reinforced to render them self-supporting. For the reasons given above, modifications and changes are deemed to reside within the scope of the present invention as defined in the annexed claims.
